Signs your boiler needs replacing rather than repairing
June 2, 2026
When your boiler starts playing up, the first question is always the same. Do you repair it or replace it? As Gas Safe registered engineers covering Guildford and the surrounding Surrey towns, we are asked this every week, so here is how we think about it honestly.
Your boiler is over twelve years old
Older boilers are far less efficient than a modern A rated unit. If yours is well over a decade old and needs a costly repair, that money is often better put toward a new boiler that will cut your bills from day one.
Repairs are becoming frequent
One repair is normal. Three call outs in a year usually means the boiler is on its way out, and the running total of repair bills can quickly exceed the cost of replacing it.
Rising energy bills
If your heating bills keep climbing while your usage stays the same, an inefficient boiler is often the cause. A new energy efficient boiler with the right controls can make a real difference.
